 One solution proposed by US officials was to further reduce the armor on the lightly protected scout cars, which would compel crews to resist the temptation of using them as combat vehicles.This was not considered practical in the long run and the US eventually replaced all its scout cars with unarmored utility vehicles such as the jeep.In 1940, the British Army defined a "scout car" as an armored car for observation, intelligence-gathering and other elements of passive reconnaissance.
